1139734 - Jerky Video Playback

Status: RESOLVED INVALID

(Core :: Audio/Video: Playback, defect)

Description

Attachment: Visaul Example of Video Bug

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:36.0) Gecko/20100101 Firefox/36.0
Build ID: 20150222232811

Steps to reproduce:

Going to various websites with video playback
Two examples:
DeviantART Film (EX: http://adreos.deviantart.com/art/Pygmalion-108438470 )
Imgur (EX: http://imgur.com/gallery/NM5ZU )
This problem does not occur on youtube.

I have tested this with all add-on removed, all personal settings removed, and a complete wipe and reinstall of firefox. No change, video playback remains jerky. 


Actual results:

The problem is while the audio is fine, the video playback is jerky and eratic. This started after I updated firefox to the (at the time of this post) current version. 36 Branch.

Please see attached video file for visual example.


Expected results:

Video playback should be smooth and fluid with the audio (When audio present)

http://imgur.com/gallery/NM5ZU has 4 videos (webm, if we believe the URL) and is quite demanding CPU-wise. It plays fine here (taking 3+ cores of my Mac, but that's bug 1133633 I think).

Do you have 100% CPU usage when playing this in Firefox? What's Chrome's usage?
